| Name | XTP diphosphatase activity |
| ID | GO_0036222 |
| collection_id | Molecular function |
| Alternative ID | GO:0103024 |
| Exact synonym | XTP pyrophosphohydrolase activity, XTPase activity |
| Description | Catalysis of the reaction: XTP + H2O = XMP + H+ + diphosphate. |
| Related synonym | XTP/dITP diphosphatase, hypoxanthine/xanthine dNTP pyrophosphatase |
| Comment | While XTP is not produced by cells, deamination of purine bases can result in accumulation of such nucleotides as ITP, dITP, XTP, and dXTP. XTPase contributes to the removal of these abnormal bases from the cellular pool of nucleotide triphosphates. |
